I've build my self a pc for my car last year, this was my 1st DIY work...i still have it still working fine..and not much cash was spent on it.... the only thing that cost me at that time was the in dash TFT lcd...got it from Brothers, using the tv out on the GC. The case was made from an acrylic left overs from a signboard i had lying around...it is running on a P4 2.6, MSI micro ATX mainboard, HDD from a WD notebook HDD. Have 1 120mm vizo uv and 80mm vizo uv fan for cooling. In day time the temp will get as high as 49c, well i'm using the stock Intel fans...haven't change to any aftermarket ones, ram is a DDR 512 from Kingston and the psu i have to mod it a bit. No keyboard is attached to my cpu..only using a logitech wireless mouse. As logn as it can play MP3 and any movie file format...i'm good
